Explanation

Formula: Ampere-hours = Millicoulombs × 2.78e-7. Why: ampere-hour units convert to charge through current over time, with 1 Ah = 3600 C exactly and 1 mAh = 3.6 C exactly, while coulomb-prefixed units scale by exact powers of ten.

Millicoulombs (mC): an SI-prefixed electric-charge unit equal to one thousandth of a coulomb.

Ampere-hours (Ah): a larger electric-charge unit commonly used for battery capacity because it expresses current delivered over time.

This route is useful when converting very small SI charge quantities into battery-capacity style units while keeping the same underlying electric charge.

This conversion is purely multiplicative with no offset because both units reduce exactly to coulombs under the same electric-charge model.
